SIMON LAKE, OF MILFORD, CONNECTICUT ROOF OR THE LIKE STRUCTURE.

Original application filed August 20, 1924, Serial No 733,208, new Patent No. 1,562,706, granted November 24, 1925. Divided and this application filed October 27, 1925. Serial No. 65,150.

This case is a division of my application, Serial No. 733,208, filed August 20, 1924:, now Patent No. 1,562,706, granted November 24, 1925.

The object of this invention is to provide a rbof or the like structure of concrete or other'suitable plastic material, having applied thereto, and preferably imbedded therein, surface finishing members of such a nature as to form an exterior surface of a permanent Water-proof character.

The invention consists in a roof or the lik structure formed preferably of preformed slabs of concrete or other plastic material, having incorporated therewith slates, tiles or other surface finish members, forming an integral part of the structure and providing upon the outer surface thereof a finish substantially the same in appearance as that of the ordinary slate or tile roof or the like, but having an advantage thereover in that the slates or tiles are permanently applied to the slabs forming the structure and are so supported thereby and afiixed thereto as to greatly enhance their weather-proofing qualities and durability, and avoid breakage, as I will proceed now to explain and finally claim. i

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a'fragmentary perspective view of a portion of a roof constructed in accordance with my invention. Fig. 2 is a fragmentary sectional detail upon a larger scale,

taken on the line 22 of Fig. 3, and showing the arrangement of the surface finish members or slates or tiles upon the structure. Fig. 3 is a section taken on the line 33 of Fig. 2. Fig. 4 is a fragmentary perspective view of a pallet suitable for the casting of slabs embodying my invention. Fig. 5 is a transverse vertical section of a finished slab upon the pallet. Fig. 6 is 'a section taken on line 66 of Fig. 5.

My invention is ada ted particularly for use in combination wit preformed roof or wall slabs made in accordance with the invention of my application hereinbeforementioned, but it is obvious that its usefulness is not limited thereto, and that it may be used in'connection with-any roof or the like structure, formed ofconcrete or other plastic material, which lends itself to the features of the method of manufacture hereinafter pointed out.

As shown in the drawings, I imbed in the plastic of the roof slab aor the like, during the process of its formation, a plurality of slates or tiles 1 forming the outer or surfacefinish of the roof or the like, and arranged in staggered relation so as to break joints, as is'customary in roofs of this type, Whereby, in appearance, the roof is substantially the same as a slate or tile roof constructed in accordance With ordinary practice.

Beneath the adjacent edges 2 of the slates or tiles, and spaced therefrom so as to be completely imbedded in the plastic of the structure, I provide breaker strips 3, of tile, slate, glass, copper, or'other suitablesmaterial having a coefiicient of'eXpa-nsion substantially the same as that of the concrete or other plastic. These breaker strips 3 seal the joints between the slates or tiles 1, and,

as will be' seen, particularly by reference to Figs. 1, 3, 4.- and 5, the upper ends 4 of the slates or tiles underlie the lower ends 5 of the slates or tiles arranged above them, thus providing the customary overlapping at the longitudinal joints of theslates or tiles.

The slates or tiles may be incorporated in a preformed roof slab of the type described in .my patent above mentioned, which, when finished, is applied to a building, by arranging them, face down, upon a pallet b, (see Figs. 4, 5 and 6) provided with surface members 6 of such conformation as to align them in courses and at the desired angle or cant to provide for the customarylap, then positioning a suitable mold box 7 upon the pallet to define the shape of the slab, then pour ing a thin layer of concrete, having prefer.- ably incorporated with it a water-proofing material, upon the exposed'surfaces of the slates or tiles. Before this layer of. concrete has set the breaker strips are positioned in it inproper relation to the edges 2 of the slates or tiles, and thereafter the completing of the.

formation of the slap is carried out as described in my Patent No. 1,562,707, dated November 24:, 1925.-

Inthis manner it will be seen that I produce a preformed roof or the like slab which, when removed from the pallet and turned over, presents an outer finish surface composed of slates or tiles arranged in the customary, approved manner and in appearance substantially the same as the ordinary slate or tile roof, but having marked advanta es thereover. I

inasmuch as the slates or tiles are incorpo rated in the roof or the like structure while the material thereof is plastic, a bond between them and the structure itself is formed of such atenacious nature that separation of the slates or tiles from the structure and derangementvthereof upon the same is practically impossible. Moreover, due to the unbroken contact of the plastic of the structure with the whole under surface of each'of the slates or tiles, a support for each of the tiles is provided which makes remote the possibility of the breaking of same by impact of bodies or by blows struck upon their exposed surfaces.

Furthermore, the roof will, be fireproof, and all of the materials used in its formation having substantially the same coefiicient of expansion there will be no tendency to form cracks or fractures under the influence of heat and cold."

A roof or the like constructed in accordance with my invention has qualities-of permanence' not heretofore attained in structures of this character, and has advantages over ordinary concrete, slate, tile and the like roofs in that it combines with the per-.

manence of the concrete roof, the water and weatherproof features of the slate, tile or the like roof. It moreover has the advantage over the latter in'that the slates or tiles are permanently afiixed and imbedded in the concrete.

Various changes are contemplated as within the principle of the invention and the scope of the following claims.

'What I claim is 3. A preformed roof slab or the like structure of plastic material, including an exterior surface composed of a plurality of surams cent courses overlapping, and breaker strips arranged beneath the adjacent edges of the members of each course, said surface finish members and said breaker strips being permanently bonded with the material of the structure and said material extending between and separating all of said surface finish members from each other.

1. A preformed roof slab or the like structure of plastic material, including an exterior surface composed of a plurality of surface finish members arranged in courses one above another and. with the edges of adjacent courses overlapping, said surface finish members being permanently bonded with the material of the structure.

2. A preformed roof slab or the like structure of plastic material, including an exterior surface composed of a plurality of surface finish members arranged in courses one above the other and with the edges of adja cent courses overlapping, said surface finish material of the structure and said material members being permanently bonded with the extending between and separating all of said surface finish members from each other. In testimony whereof I have hereunto set my hand this-26thday of October, A. D. 35
